In the Arboretum you'll occasionally see a turtle or two sunning themselves on the sides of the creek. There are actually quite a few turtles in the creek. Really any permanent pond or stream in Davis has a lot of turtles in it and if you know what to look for you'll probably spot them. The cool looking stubby ones with the tails are the native Western Pond Turtles and the more commonly seen stripey ones are the prolific and invasive Red Eared Sliders. They will hiss at you and are pretty ornery little bastages
